2011-8869. Approval and Promulgation of Air Quality Implementation Plans; Indiana

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve a request submitted by the Indiana Department of Environmental Management on November 24, 2010, to revise the Indiana State Implementation Plan (SIP) under the Clean Air Act. Indiana submitted revisions to the particulate matter (PM) and sulfur dioxide (SO₂) limits for Cargill, Incorporated (Cargill) at its facility in Hammond (Lake County), Indiana. Indiana's SO₂ revisions tighten emission limits for some existing units at Cargill's Hammond facility and remove the references to other emission units that are no longer in operation, in accordance with the terms of a September 2005 Federal consent decree. The PM revisions reflect the permanent shutdown of and changes in unit identification for other Cargill units.

SUPPLEMENTARY INFORMATION:

In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule which is located in the Rules section of this Federal Register.
